It’s no coincidence that these two countries are such breeding grounds for Islamic terrorism. Both are home to some of the most radicalized and ostracized Muslim neighborhoods on the continent; Molenbeek in Brussels, and the banlieues in Paris…

In the refugee crisis, ISIS has recognized a golden opportunity to further its narrative of a civilizational war between Islam and the West—and many European leaders have played directly into the terror group’s hands. When the Polish and Bulgarian prime ministers say that they are only willing to accept Christian refugees, it gives fodder for ISIS to rally more zealots to its cause…ISIS clearly wants the European public to conflate refugees and terrorists, and it has been doing a disturbingly good job so far.

Both Trump and Cruz are providing ISIS with fodder for their “civilizational war between Islam and the West” by suggesting that we should stop immigration of Muslims to this country. And of course, Trump proposes things like torture as well as the targeting of terrorists’ families.

But it was the suggestion from Cruz that law enforcement should target Muslim neighborhoods that is perhaps most alarming because it is so insidious. Not only does it suggest that people should be treated like criminals based on their religious faith, Cruz made this alarming comparison yesterday.

Cruz repudiated the comparison [to Japanese internment camps] at the press conference, saying: “I understand that there are those who seek political advantage and try to raise a scary specter.”

He instead compared it to ridding neighborhoods of gang activity and law enforcement’s efforts “to take them off the street.”

In other words, he is suggesting that living in a Muslim neighborhood (however that is defined) means you should be treated the same as a gang member. A spokesman for the NYPD tweeted an important response.

There are those who suggest that one of the reasons four attacks in Europe since 9/11 have killed 426 people, while terrorism has claimed the lives of 45 people in the United States is that Muslim neighborhoods in this country have not been radicalized and ostracized. Republicans like Ted Cruz and Donald Trump want to change all that…and make us less safe.

Five former generals have said the same thing about earlier comments. And, former Secretary of Defense Robert Gates, who worked for Bush and Obama, said Cruz and Trump don’t know what they are talking about with respect to fighting ISIS.
